Earl Diamond - Solid Brass Door Viewer Peephole, 220-Degree Security Peephole with Heavy Duty Rotating Privacy Cover for 1-21/32" to 2-1/8" Doors for Home Office Hotel - Modern Black Finish

Works perfectly. Wide enough view for my application. 5 Stars

Oh my goodness this is absolutely amazing. It was very inexpensive. The instructions are very clear and it actually took about 5 minutes to put in. I can't believe how clear the view is. The inside looks great but outside is really beautiful!! No kidding. I can see so far beyond the house across the street. I guess no one is going to be coming near my front door anymore without me knowing who is out there now.

Best door viewer that I've tried. The large diameter tube and the rear lens give a clear wide view. Don't have to put eye real close to see. All metal, well made. Like the push up cover. Looks good from inside.Obviously the 220 degree view is inaccurate (a flat door only allows for 180 max) but the view is great. Must be a typo. Would buy again.

The 220 degree FOV claim is preposterous. The door itself limits you to 180 and this is more like 150 or so. But I already knew that. Otherwise the image quality is terrific. The large barrel and rear optics provide for a bright and sharp view. You get a full view even one to two inches away so you don't have to crane your neck getting your eye right on top of it.No comparison to older half-inch diameter peepholes. View is nice and linear, no parallax distortion. Very happy.

This peep hole door viewer was made to last. The glass bezels were clear and the fitment into the brass housing was secure and easy to install. I also noticed on the viewer that guests were not able to see inside as you approached your door. Excellent purchase for your safety.

We had no way of seeing who was at the other end so I invested in a little viewer to see what evil lurks out there. One needs an auger bit to get a large hole in place. Followed by a good half round file to clean the hole so the viewer slides through. It works fairly well and serves the purpose. As crime improves we may have to improvise and get an electronic battery driven view finder. This way one can see from another perspective and not be right at the door. The way things are now, I fear someone may shoot through the door directly at the viewer, if it's not opened up or quick enough. Times have changed.So I can recommend this viewfinder.

I installed two of these--one for my front, one in the back door. Easy installation, but if you have a steel, hollow-core door, I would strongly suggest you get a graduated (cone-shaped) bit that is able to handle metal because even though the layers of steel are thin on such doors, the job is easier with the proper bit. Beyond that, installation was quick and easy. The improved view is great and you *cannot* see into the house from the outside, though the "speak-easy" type slide-over cover is an added feature and if your door faces due east or due west, will keep light out if that's what you wish.

It's almost twice the size of the one I got at the big-box years ago, so it gathers almost four times the light, for a bright image. The shutter is why I wanted it, though. With the shutter closed, no one can see if there's anyone behind the door.
